Answer:11.0325 J

Step-by-step explanation:The formula for calculating Potential Energy is:

P.E. = mass * acceleration due to gravity * height

where mass is in kg

acceleration due to gravity is a constant at the surface of the earth = 9.8 m/sec^2

and height is in meters

Here:

P.E. = 0.75 kg * 9.8 meters/sec^2 * 1.5 meters

P.E. = 11.0325 kg*m^2/sec^2

Now kg*m^2/sec^2 = joules

so the answer is 11.0325 joules
